MOX Switch
Pressing this button engages the PTT (Push to Talk)
circuit, to activate the transmitter. It must be in the
undepressed position for reception. This switch repli-
cates the action of the Push to Talk (PTT) switch on
the microphone. When engaging the MOX switch,
or otherwise causing a transmission to be started, be
certain you have either an antenna or 50-Ohm dummy
load connected to the selected Antenna jack.
VOX Switch
VOX Operation: This button enables automatic voice-
actuated transmitter switching in the SSB, AM, and
FM modes. While activated, the LED inside this but-
ton glows red. The controls affecting VOX operation
are the front panel's VOX and DELAY knobs
(see section ( ) below. By proper adjustment of these
controls, hands-free voice-actuated operation is pos-
sible.
DIM Switch
Press this button to lower the illumination intensity of
the analog meters, the frequency display, and the TFT.
Press it once more to restore full brightness.
Advice
Menu Items "DISPLAY 014 DIMMER-METER" and
"DISPLAY 015 DIMMER-VFD" allow you to con-
figure the dimming levels for the analog meters and
the frequency display/TFT independently, so you can
customize the brightness levels.

PHONES Jack
A 1/4-inch, 3-contact jack accepts either monaural or
stereo headphones with 2- or 3-contact plugs. When a
plug is inserted, the loudspeaker is disabled. With ste-
reo headphones such as the optional YH-77STA, you
can monitor both Main (VFO-A) and Sub (VFO-B)
receiver channels at the same time during Dual Re-
ceive operation.
Note: When wearing headphones, we recommend that
you turn the AF Gain levels down to their lowest set-
tings before turning power on, to minimize the impact
on your hearing caused by audio "pops" during switch-
on.

POWER Switch

Press and hold in this switch for two seconds to turn
the transceiver on, after first setting the rear panel
Power switch to the " " position. Press and hold in
this switch for two seconds, similarly, to turn the trans-
ceiver off. If the rear panel's Power switch is set to the
" " position, the front panel POWER switch will
not function.
Advice
This is the actual power On/Off switch for turning on
the transceiver. When the rear panel's Power switch is
set to the " " position, power is supplied to the OCXO
to stabilize the reference oscillator, and the remainder
of the transceiver is set in a "stand-by" mode, await-
ing the command for the transceiver to switch on via
the front panel POWER switch. For further infor-
mation on the rear panel Power switch, please see the
discussion on page 36.
